One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
** During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.
†
Seagate does not recommend operating at sustained case temperatures above 60°C.
Operating at higher temperatures will reduce useful life of the product.

LBA mode
When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where n is the number of
guaranteed sectors as defined above.
See Section 4.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit addressing support
of drives with capacities over 137GB.

Maximum rate of 300TB/year.
Workloads exceeding the annualized rate may degrade the drive MTBF and impact product reli-
ability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours.
Workload Rate = TB transferred * (8760 / recorded power on hours).
